Abstract

Refractories obtained by molding a refractory raw material composition containing a refractory raw material including graphite grains having an average grain size of 500 nm or less or a refractory raw material including graphite grains obtained by graphitizing carbon black and a refractory filler, Or refractories containing carbonaceous grains (A) selected from carbon black or graphite grains obtained by graphitizing carbon black and having a DBP absorption (x) of 80 ml/100 g or more, carbonaceous grains (B) selected from carbon black and graphite grains obtained by graphitizing carbon black and having a DBP absorption (x) of less than 80 ml/100 g, and a refractory filler. Refractories excellent in corrosion resistance, oxidation resistance and thermal shock resistance, especially carbon-contained refractories having a low carbon content are thereby provided. <IMAGE>
